I quit cold-turkey around 3 years ago. Caffeine started to affect me differently the older I got, and it wasn't until I was almost hospitalized from dehydration during a house move that I realized I was perhaps a little too dependent on it.

The following couple of weeks after quitting was hell. Migraines, shakes, generally feeling awful. I doubted my decision, but powered through, and am thankful I did.

Waking up is easier, going to sleep is easier, and personally I wasn't a fan of the adrenaline rush feeling I would get after drinking coffee. Your mileage may vary, but if you're getting older and feeling jittery then definitely give it a try.
